WORKSHOP PROJECT: FERRIS WHEEL

Ferris wheel: creating a Ferris wheel with light!

Project Description The Ferris wheel should be able to spin both ways while remaining lit. The Ferris wheel structure will be completed with cardboard and attached with wood glue.

There will be two circuits. The first will be the motor circuit controlled through a switch and a switchboard that will allow the Ferris wheel to spin in both directions. The circuit will be powered by a 4,5 V battery.

Materials -1 beech pulley, 4mm with a 50 mm hole -2 cylindrical headed screws M4x 50 mm -18 semi round headed screws M2x 10mm -2 separation washers -1 reduction motor 23:1 with a double axis and 4mm -8 small bulbs (red, green, yellow and transparent) E 10; 3,5 V and 0,2 A -8 small bulb holders -2 switches -1 switch with 6 connections -2 4,5V batteries -1 Transmissioncable -Wood glue -1 solder to weld

Tools -Saw to make angles -Electric saw -Hand drill -Welder

Directions A Ferris wheel is formed by two perfectly equal octagonal sides.

To calculate the measurements of the two sides, you must keep in mind that the octagon is formed within a circumference of a 20 cm radius. The sides of the octagon will be made of cardboard (5 mm x 18 mm x 2 000 mm). Once you have the measurements of the sides and angles of the octagon, you must cut the 8 sides of the octagon. In the middle of each side, you must make a hole.

Each side of the Ferris wheel will have a central 5,5 cm disc made of cardboard as well as a central hole.

Each of the 8 radii will be made of cardboard and measure 17 cm. Once you have the pieces of every face, you can start to glue them together. Side Central disc

When both sides are completed, join them with a central cylinder 6 cm in height and 8 pieces that will support the radii of each side.

In the 8 pieces, you must screw in the 8 small bulb holders. For this reason, it is very important that before you put the pieces together, you must install the electricity for the light bulbs. Once the electricity is installed, you can join the two sides.

In one of the two sides, you must glue the pulley in which you will insert the transmission cable that will make the Ferris wheel spin from the power of the motor.

The supports will be made of pieces of cardboard (9,5 mm x 9,5 mm x 2 000 mm).

The supports Each support will be added to the Ferris wheel using two cylindrical headed screws M4 x 50 mm that will go through the support, the pulley (only on the side to which it is glued) and the structure of the Ferris wheel. You must leave a space between the support and the Ferris wheel so that when it spins, they will not brush together.
